Right WiFi modul loaded only in Live USB mode, not when OS installed on hard drive

Question

My laptop has Broadcom BCM 43228 wifi chip. I know that a right module for this chip is wl. In live mode when I do:

lsmod | grep b43

I get nothing which is good, b43 is not the driver I need for this chip. Then I add wl module like this. Because I'm not connected to the internet, I guess apt-get installs it from the USB.

sudo apt-get install bcmwl-kernel-source

After that I can see my wifi SSID and internet connection works. When I do:

lsmod | grep wl

I get:

wl                   6365184  0
cfg80211              548864  2 wl,mac80211

which means wl is loaded and everything is fine. However when I install Ubuntu, b43 is loaded, wifi isn't working and I can't install wl module. It says that I don't have internet connection. Ethernet is not an option, I don't have a wire close. Bluetooth and mobile tethering is also not an option right now.

Is there an easy solution? Blacklist b43, install wl from USB? I see that bcmwl on the USB drive but when I try dpkg -i bcmwl-... it throws me dependencies errors.

I tried that, but it says gcc is not installed http://imgur.com/mZ5LClh Could the solution be not to install updated kernel when installing on hard disk? — Hrvoje T, Apr 03 '16 at 13:52
That is weird, because these packages should be installed by default. So this is probably not Ubuntu. — Pilot6, Apr 03 '16 at 13:54
@Pilot6 gcc and compilers aren't auto loaded. build-essential getting installed includes the compilers - default systems don't get it if I remember the layout of the ISOs and meta packages. — Thomas Ward, Apr 03 '16 at 16:40
It is Ubuntu with KDE, Kubuntu. So I don't need to ne helped if it's not Unity? — Hrvoje T, Apr 03 '16 at 16:57
The easiest way is to connect to internet by wire and install the driver. — Pilot6, Apr 03 '16 at 17:17
Yes I know, but right now I don't have access to wire and this is not a solution because in live mode everything works, so all files are here. — Hrvoje T, Apr 03 '16 at 19:52
